Title: Industrial robot positioning system - has speed and acceleration controls with servo mechanism for accurate fine control
Inventor: KUNO TOSHITAKA
IPC: B25J9/16
Filed: 1974-12-06
Abstract: The positioning system has a position signal-adjustment device for producing a position command signal which causes an operating or position member of a series to be brought directly or in stages into a number of required positions. A speed control device converts the position command signal into one which, at a predetermined speed, increases or decreases. An acceleration control converts an excessively strong fluctuating part of the output signal of the speed control into a smooth compensated signal. A servo-positioning mechanism which receives the acceleration control output signal as input signal, provides a high feed-back smoothing amplification, but no time delay for the acceleration control, so that the positioning of the operating or position member is achieved with a higher degree of accuracy.

Title: Bonding metallic bodies using insert - which forms reducing atmos. preventing oxide formation
Inventor: OSHIDA YOSHIKI
IPC: B23K20/16
Filed: 1975-01-16
Abstract: Metal bodies are bonded together by sandwiching an insert that forms a reducing atmos on bonding, between the bodies, applying pressure to the assembly to pressure bond the material with super-plastic flow at raised temps. and simultaneously with the application of pressure alternately heating and cooling the assembly through a temp. range above and below the transformation temps(s). of the metal until a permanent bond is formed. In bonding knurled pipes, boiler steel pipes, cast iron parts etc. Even if unbonded parts are left on the surface, the high temps. do not result in oxide formation because of the presence of the reducing atmos. The compression stress can therefore be lowered and the established bonding is a strong one.

Title: Automatic coin handling mechanism with antijamming facility - reverses drum drive to avert jamming using clutch mechanism
Inventor: LANGKAIT OTTO
IPC: G07D9/00
Filed: 1975-06-27
Abstract: An automatic coin handling mechanism which arranged coins of one size into a neat column for application to coin sorting machines has an anti-jamming facility. The mechanism is in the form of a rotating drum (2) into which the coins (12) fall in a random manner. At the bottom of the drum is a plate (3) in which holes (3a) of the correct size allow tidy streams of coins to emerge from the base of the drum, which is mounted obliquely. The drum is driven through a shaft (1) from a motor coupled to it by a pulley wheel (6) which is coupled to the shaft by a spring clutch arrangement. When a jam occurs this clutch releases slightly, operating a switch (11) which reverses the motor drive and so reverses the direction of rotation of the drum. Serious jamming is thus averted.
